Abstract

Die Erfindung betrifft einen Weg-Winkel-Sensor (1), insbesondere zur Bestimmung eines eingelegten Ganges im Kraftfahrzeugbereich. Um einen solchen Weg-Winkel-Sensor (1) derart auszugestalten und weiterzubilden, daß er preiswert hergestellt werden kann, er einen einfachen und robusten Aufbau aufweist, sein Einsatz einfach und preiswert ist und er eine hohe Meßgenauigkeit aufweist, wird erfindungsgemäß vorgeschlagen, daß er vier Meßspulen (3, 4, 5, 6), die in einer X-Y-Ebene auf einem Spulenträger (2) in einem Winkel von 90° zueinander angeordnet und an eine Auswerteelektronik angeschlossen sind, und ein Target (7) aufweist, das im wesentlichen parallel zu der X-Y-Ebene relativ zu den Meßspulen (3, 4, 5, 6) bewegbar ist und dadurch in den Meßspulen (3, 4, 5, 6) Spannungen (Uind3, Uind4, Uind5, Uind6) induziert, aus denen die Auswerteelektronik den zurückgelegten Weg s in Y-Richtung und den Winkel α des Target (7) in einer Z-X-Ebene ermittelt.

The invention relates to a displacement-angle sensor (1), in particular for determining an engaged gear in the motor vehicle sector. In order to design and develop such a displacement-angle sensor (1) in such a way that it can be manufactured inexpensively, it has a simple and robust construction, its use is simple and inexpensive and it has a high measurement accuracy, the invention proposes that it four measuring coils (3, 4, 5, 6), which are arranged in an XY plane on a coil support (2) at an angle of 90 ° to one another and connected to evaluation electronics, and has a target (7) which is essentially parallel to the XY plane relative to the measuring coils (3, 4, 5, 6) and thereby induces voltages (U ind3 , U ind4 , U ind5 , U ind6 ) in the measuring coils (3, 4, 5, 6) , from which the evaluation electronics determine the distance s traveled in the Y direction and the angle α of the target (7) in a ZX plane.
